A criminal background check is a process used to verify an individual's criminal history. This check typically includes information about any past arrests, convictions, and sometimes pending charges. Employers, landlords, and organizations often use these checks to assess the suitability of a person for a job, rental agreement, or volunteer position. The information in a criminal background check is usually obtained from various sources, including law enforcement agencies and court records. The results can help ensure safety and security in workplaces and communities by identifying individuals who may pose a risk due to their past behavior.
